To all whom it may concern.-

Be it known that we, ARMAND MIEG, a subject of the King of Bavaria, and a resident of Leipsic, Saxony, and HUGO BISCHOFF, a subject of the King of Bavaria, and a resident of the city of Diirkheim, Bavaria, Germany,have invented certain new and usefullmprovements in the Manufacture of Wolfram Projectiles, (for which we have obtained patents in the to following countries to wit: in Germany, No. 22,891, dated November 26, 1882; in France, No. 163,389,dated July 19, 1884; in England, No. 1,849, datedApril12, 1883; in Austria, No. 10,686, tome 33, folio 1360, and Hungary, No. 29,692,tome XVII, folio 1345, dated both July 13,1883; in Italy, Reg. Gen. folio XVIII, No.

16,886, and Reg. attest volume XXXIII, No. 330, dated June 30, 1884, and in Belgium, No. 60,734, dated March 13, 1883,) of which the following is a specification.

I The object of our invention is to produce'a projectile made of metallic tungsten or wolfram (chemical symbol W) instead of metallic cast lead, as heretofore.

2 5 Referring to the drawings, Figure'l is a side view of our projectile, showing the same inserted in a cartridge. Fig. 2 is a sectional view of same.

A is the projectile; B, the cartridge.

3o Heretofore projectiles have been made of cast lead; but we make our projectile of tungsten or Wolfram, as it yields a particularly low trajectory or curve by reason of its high specificgravity,which is 17.4. It also has a greater 7 5 penetrating power than lead.

The general composition of the cartridge B may remain unchanged.

We do not confine ourselves to the size or shape of the projectile, as any desirable deviation may be made. In order to attain the 0 same effect as with projectiles made of lead, together with increased security and greater range, our projectile, made of tungsten or Wolfram, may be made of a smaller size. This is of great importance, as the caliber of firearms can in consequence be reduced.

The projectile can be made of metallic tung sten or Wolfram either cast or pressed. It may, also, be made from powdered tungsten or Wolfram produced either by mechanical or 'our invention We have signed our names in the presence of two subscribing witnesses.
